Handheld probe shows great promise for oral cancer detection

A team of American researchers has created a portable, miniature microscope in the hope of reducing the time taken to diagnose oral cancer.

The probe uses a laser to illuminate areas of the sample and can view beneath the surface of tissue, creating full 3-D images. It can also take a series of images and layer them on top of each other, offering a large field-of-view.

The probe could be used by dentists to diagnose oral cancer in real-time or as a surgical guidance tool; it could also be used to screen for early-stage cancer cells.
